...1.1 VIRTUAL PRIVATE NETWORK: A VPN is a method to connect the office network (for example Private network) from the client systems (for example home Laptop) via public network (for example an Internet). A VPN tunnelling will have the advantages of dial-up connection to a dial-up server, because of the flexibility of an Internet connection and also the ease access of an Internet connection. By using an Internet connection the client can connect to the server or the resource in all over the world, like accessing the office desktop from home through an Internet connection. The computer and the office desktop can communicate at full Internet speed or very high speed if you have an Internet connection as cable or digital subscriber line (DSL).

...culture is able to impact design and usage of mobile devices; and how text and multimedia messaging present new challenges for policymakers. With regard to this proposal, the first article discusses how mobile internet usage in rural areas has lagged behind the rest of the population. The article also points out that while there have been improvements in coverage, the build-out of mobile networks has typically been less extensive than in urban areas. Solution: Mobile/Wireless Internet Its Use: Mobile Internet service could potentially be used in conjunction with site-to-site VPN connections, in order to establish connectivity from the remote locations to the hospital. Application: Mobile Internet hotspot devices could be used to get Internet access in Northeastern Health Services’ remote offices. In conjuction with these hotspots, firewall appliances can be used to establish a site-to-site VPN connection from each of the offices to the hospital’s radiology department. However, because of the lower levels of network build-out in rural areas, there is an increased likelihood of poor network coverage in some or all of these rural locations. DeBeer, M., & Williams, J. D. (2004). Unwiring With Wi-Fi and Cellular Technologies. Behavioral Health Management, 24(1), 18-22. The authors of this article explain the differences between wi-fi and cellular Internet access, and they also discuss the security...

...Small Network Sales Proposal Bill Stewart Strayer University June 11, 2011 My neighbor is starting a small billing business and has asked me to price out and design network for him. He will be starting from scratch and in talking to him about his needs, I have determined that what he wants is the following; he needs a server that will support at least 3 users. Also he wants 2 workstations and 2 laptops. He wants Wi-Fi to connect all of this plus Internet access and multiple email addresses. Also he wants this network to be totally secure as his coming is going to do medical billing procedures. Here are my suggestions to him as described in this proposal. Since this small business is interested in a dedicated server, I am suggesting the HP ProLiant N40L 1P 2GB-U Emb SATA NHP 250GB LFF 150W PS Cube MicroServer. This server will meet all of the client's needs at this point. The price is relatively small and the client will find that this system is easy to operate and it is simple to administer to. Also this small server is designed to make adding drives or peripherals a minimal effort. Obviously the space saving design will make it ideal for a small office. This server is also reliable and it's also is expandable. Its error checking and correction (ECC) memory minimizes the likelihood of memory corruption. This server comes with AMD Turion™ II Neo N40L processor (1.5 GHz, 15W, 2MB) and being RAID 0 and 1, it prevents data loss and ensures around the clock reliability. The...

...Best Practices for Network Security DaMarcus Forney American Military University June 19, 2013 Best Practices for Network Security It's no secret that there are millions of networks around the world. Today, networks are relatively easy to create. A network can be something as simple as two computers or hosts being connected together. They can also be very complex and consists of thousands of different network objects such as routers, servers, printers, and workstations. The Internet has revolutionized the way networks can be used. It has created endless possibilities for network technology as a whole and it's users. The first networks were intranet networks. All of the objects running on a intranet, including the infrastructure itself were locally owned and managed. As more and more information was being stored on intranets the need to secure them became more important. The good thing about intranets is that majority of the threats associated with them are internal, making them easy to secure. This can not be said about external networks such as the Internet. The Internet introduced threats that can reside from anywhere in the world. This put greater focus on network security. Securing networks that have access to the Internet is a never ending job. The sad part about securing a network is that a network will never be 100 percent secure. There will always be risks associated with every type of network. One can reduce those risks...

...Running head: NETWORK DESIGN FOR ACME Network Design for Acme Manufacturing Learning Team A: [your team members] University of Phoenix Intro To WAN Technologies NTC/242 Acme Manufacturing Network Design Introduction As a network consultant hired by Acme Manufacturing, the company has asked Team A to develop a new networking design for their expanding business. The description below describes the key steps involved in developing a WAN for Acme Manufacturing. The company has six different buildings in six different locations throughout the world which need to be networked collectively. All the remote locations need to be able to communicate effectively with the main headquarters which is located in Atlanta, Georgia. The two buildings which house the headquarters are located across the street from each other. One building is used solely for corporate operations while the other building is used for staffing the sales and engineering department. Network Topology The best choice for the company would be to use a LAN with routers and Ethernet cables. This is a logical choice because the speeds of the network will be far superior and will help to reduce the total cost of the network. The three distribution buildings are located in Chicago, Phoenix, and New York. It is not feasible to run cabling to theses locations due to cost, so using T3 leased lines to communicate is the recommended method to connect the buildings with headquarters...
